Acute polyarthritis revealing celiac disease of the elderly

Introduction: Celiac disease (CD) is an autoimmune disease that typically occurs in childhood and young age. Late-onset forms (after 60 years) are rare and often underestimated in current medical practice, as is joint damage during this disease. We report an original case of CD in an elderly patient revealed by acute polyarthritis. Observation: A 62-year-old patient with no significant pathological history was explored for acute polyarthritis of both large and small joints. The physical examination noted synovitis of the hands and wrists without articular deformities, and a marked mucocutaneous pallor. The biology revealed a microcytic anemia at 8 g/dl with stigmas of malabsorption (low cholesterol and hypocalcemia). No inflammatory syndrome was noted. Joint X-rays were without abnormalities. Immunological tests for chronic inflammatory rheumatisms were negative. Gastroduodenal fibroscopy was performed and histological examination of duodenal biopsies showed diffuse villous atrophy with marked inflammatory infiltrate. Anti- endomysium and anti-transglutaminase antibodies were positive confirming the diagnosis of CD. Under gluten-free diet, the evolution was favorable with totally disappearance of articular signs. Conclusion: Joint manifestations during CD are rare. The revealing forms are exceptional and can make a differential diagnosis with chronic inflammatory rheumatism, in particular that associations with CD was described. CD deserves to be evoked in front of any unexplained arthritis of the elderly, even without any specific digestive symptomatology of this disease.
